AI Article Synopsis
- The study introduces an aminosilicone solvent mix specifically designed to capture CO(2), utilizing a hydroxyether co-solvent to keep it in a liquid state for better absorption.
- The solvent system was tested and successfully regenerated over 6 cycles, showing a 25-50% improvement in CO(2) capacity compared to 30% MEA.
- Additionally, the research validated continuous CO(2) absorption and found that predictions for reaction heats matched well with experimental data.
Article Abstract
This work describes the first report of the use of an aminosilicone solvent mix for the capture of CO(2). To maintain a liquid state, a hydroxyether co-solvent was employed which allowed enhanced physisorption of CO(2) in the solvent mixture. Regeneration of the capture solvent system was demonstrated over 6 cycles and absorption isotherms indicate a 25-50 % increase in dynamic CO(2) capacity over 30 % MEA. In addition, proof of concept for continuous CO(2) absorption was verified. Additionally, modeling to predict heats of reaction of aminosilicone solvents with CO(2) was in good agreement with experimental results.
